hoping you're still planning to work on this! As simple as it is, pairing it with things like pixel-art creation programs and pixel-art-to-voxel things could allow for some absolutely awesome renders in MagicaVoxel or even Blender, or just for game assets for whatever engine someone may use! I'd actually love to use this for that very purpose, however it's a tad too simple as-is at this moment for me to do too many interesting things with it, but I do hope you plan to continue with it!
